Okay first off. You want to combine like terms. 

2.75-1.5=1.25j 
2.25+3=5.25

Now you just fit those two answers into the final answer and you have:

1.25j+5.25.

(14-8) × (15-4) <br> Use the order of operations to find the value of each expression
Yuliya22 [10]

Answer:

66

Step-by-step explanation:

the order of operations is the acronym PEMDAS which stands for:

P: Parentheses

E: Exponents

M & D: Multiplication and Division

A & S: Addition and Subtraction

we do these in order, from left to right in the equation

for the equation (14 - 8) x (15 - 4), we would start with solving the parentheses

there are 2 sets of parentheses, so we will go from left to right in solving it:

(14 - 8) = 6

(15 - 4) = 11

we replace the values we have found from the parentheses into the equation

6 x 11

now we go through the list

we can already eliminate exponents because there are none in this equation

the next step is multiplication & division, in this equation there is only multiplication, so we multiply 6 x 11 which gives us the answer 66

there is nothing left for us to do at this point, so 66 is our final answer

PLEASE HELP ME WITH THIS <br>PLEASE EXPLAIN

When the x values are evenly spaced, as they are here, the second differences are constant when the function is quadratic.

1st table:
.. 2 -4 = -2; 1 -2 = -1; 0.5 -1 = -0.5 . . . . first differences
.. -1 -(-2) = 1; -0.5 -(-1) = 0.5 . . . . . . . . . second differences are different

2nd table:
.. 128 -135 = -7; 105 -128 = -23; 72 -105 = -33 . . . . first differences
.. -23 -(-7) = -16; -33 -(-23) = -10 . . . . . . . . . . . . . . . second differences are different

3rd table:
.. -23.2 -(-23.4) = 0.2; -23 -(-23.2) = 0.2 . . . . . first differences are constant. This is a linear function.

4th table:
.. 56 -90 = -34; 26 -56 = -30; 0 -26 = -26; -22 -0 = -22; -40 -(-22) = -18
.. -30 -(-34) = 4; -26 -(-30) = 4; -22 -(-26) = 4; -18 -(-22) = 4 . . . . second differences are constant at 4.

The 4th selection is appropriate.
